zjaber is on a distinguished road
02 x5 4.6is Tranny

My down shift from 2 to 1 is really hard.
This happens after the engine is warm and running for a while.
I spoke to tuner motorsports and they said i need a software upgrade to attempt to resolve this.
I called my bmw dealer ship and made an appointment
Is this the correct path to fixing it or should i do something else
